From VOA Learning English, this is the Health Report in Special English.

Microscopes are an important tool in identifying diseases, but they are not always easily available. Now, for a few dollars and a little work, the iPhone can become a microscope. The same is probably true of other smart phones too.

Dr. Issac Bogoch is an infectious disease specialist at Toronto General Hospital in Canada.

“We got this idea from reading some of the medical literature, and we saw that some other groups had published neat images that were taken in the laboratory using smart phones and converting them into microscopes. But we thought that this was a really neat concept and we wanted to take it to real world and practical settings.”

Dr. Bogoch is the lead investigator of a new study on the iPhone microscope. It appears in the American Journal of Tropical Medicine and Hygiene. He says he used an iPhone 4S because he happened to own one.

“But any smart phone with a decent camera and a zoom-in function should work just fine.”

Dr. Bogoch says he and his teammates then bought a ball lens online for about 8 dollars. They attached the special lens to the lens of the iPhone camera using two-sided tape. Dr. Bogoch and his colleagues from Massachusetts General Hospital and the Swiss Tropical and Public Health Institute tested the iPhone on Pemba Island in Tanzania. He says they looked for intestinal parasites in school age children.

He says the infections affect more than 1 billion people on the planet.

“We took slides. We were looking for intestinal parasites. So these are stool samples. The slide had a little bit of cellophane covering the stool sample and we put the slide very close to our ball lens, which was stuck up against the iPhone. And we were able to zoom in and we could see the parasites that we were looking for pretty easily.”

Dr. Bogoch said the results were better when the infections were more severe. But he thinks that will change when the technology improves.

Intestinal parasites include hookworms and roundworms. They can cause chronic anemia, a lack of enough iron in the blood. They also lead to malnutrition. Normally, intestinal parasites are identified by examining body waste through a traditional light microscope.

Dr. Bogoch says the next step is to improve the image quality. He says the smart phone microscope could greatly extended disease control in poor, rural areas. He says treatment for many intestinal parasites is generally widely available. He also says medical workers would be able to email an image to an expert for help in identification.

And that’s the Special English Health Report from VOA Learning English. I’m Karen Leggett.
